C# 基于UDP的局域网通信

using (UdpClient client = new UdpClient(new IPEndPoint(IPAddress.Any, Port)))
{
    IPEndPoint endpoint = new IPEndPoint(IPAddress.Any, 0);
    while (true)
    {
        Thread.Sleep(10);
        if (client.Client.Available <= 0)//可防止报错
        {
            continue;
        }

        byte[] buf = client.Receive(ref endpoint);
        string msg = Encoding.Default.GetString(buf);

        MsgParse(endpoint, msg);
    }
}

sendClient = new UdpClient(new IPEndPoint(IPAddress.Any, 0));
byte[] buf = Encoding.Default.GetBytes(str);
IPEndPoint endpoint = new IPEndPoint(IPAddress.Parse("255.255.255.255"), Port);
sendClient.Send(buf, buf.Length, endpoint);
